Trent Thornton

The Blue Jays officially added newly-acquired outfielder Derek Fisher to the roster, while also activating right-hander Trent Thornton from the injured list. Thornton is scheduled to start tonight’s game against the Orioles. Right-hander Jason Adam also had his contract selected from Triple-A.

It was a brief IL stay for Thornton, whose placement with inflammation in his throwing elbow was retroactive to July 21. Acquired from the Astros for Aledmys Diaz last winter, Thornton has shown some flashes of promise within an inconsistent season, posting a 5.45 ERA, 9.1 K/9, and 2.22 K/BB rate over 99 innings in Toronto’s rotation. He’ll continue to receive a long look at the Jays figure out their future pitching plans now that Marcus Stroman and Aaron Sanchez have both been dealt.

Adam was acquired in a minor deal with the Royals in March, though injuries have limited to just 13 1/3 total innings in the minors this season. The righty has a 4.24 ERA, 2.87 K/BB rate, and 7.8 K/9 rate over 579 1/3 career frames in the minor leagues, working almost exclusively as a relief pitcher in the last three seasons. Adam made his MLB debut last season, tossing 32 1/3 innings for Kansas City while posting a 6.12 ERA, as he allowed a whopping nine homers over his brief stint in a Royal uniform.
